Abstract
A weldment manufacturing method includes drilling that forms a hole on a workpiece, feeding a filler material to the hole and putting the filler material on a bottom of the hole, and melting the filler material by emitting a laser beam to the hole while scanning with the laser beam, so as to fill the hole with the melted filler material. By repeating the feeding and the melting, a weld repairing portion filling the hole is formed.
